Oh, I'm sure there is. But I find it easier to just top off at least once a week, with my "after top off" SG being a little on the low side. Say, 1.022 or so. That way, as it evaporates, it remains inside the acceptable zone longer.

Oh wow. Is that safe? That sounds super easy. But I was under the impression that it needs to stay bang on in the 1.024-1.025 range. If it can safely range between say 1.022-1.028 then that's easy!

Dan is right. I'm a little lazy. Fluctuations between 1.022 and 1.028 are a bit much, but I rarely go past 1.026, usually keeping ot between 1.022 and 1.025, which is perfectly safe. Very few creatures will notice that difference, though there are some that really are that sensitive.

Don't suggest an emerald crab as I've seen a lot of "horror stories" of them picking at coral and killing small slow fish/inverts even though they are considered reef safe. Unless you have a bubble algae problem you should consider one, but even then, some don't eat the bubble algae! They are what "opportunistic feeders"..when given the chance to get a meal, they just might do that.
